Step by step
Solved in 2 steps
- Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)What is the return result of a function that lacks a return statement or has an empty return statement? Example: def x(a,b): print(x) returnIn Python, write a fruitful function with comments.Then add an example of how to call the function and use its return value. Conditions: There should be no print statements. Use return statementsto give results back to main. The main function will: Accept input Pass input to other functions Receive input from other functions and then print the results.
- Please help me with my homework, in computer programming as follows: A number, a is a power of b if it is divisible by b and a/b is a power of b. Write a function called is_power that takes parameters a and b and returns True if a is a power of b. Note: you will have to think of the base case.This is python Regarding a function, which of the following is not true? The def keyword is used to create a function. A function must contain a return statement. When a function is defined, it must have parentheses. A function can contain another function.What statement about the print() function is true? A. print() has a variable number of parameters. B. print() can have only one parameter. C. print() can be used to obtain values from the keyboard. D. print() does not automatically add a line break to the display. After a function calculates a value, how does it return that value to main program where it was called? A. By including that value in a return statement. B. By using the print() function C. By storing the value in a local variable. D. Since function variables are destroyed when the function call is completed, the calculated values are destroyed as well. Where in a program should a function be defined? A. At the very end B. Immediately after the first call to the function C. Near the top of the program D. Functions do not have to be defined to be used
- def truth_value(integer): """Convert an integer into a truth value.""" # Convert 0 into False and all other integers, # including 1, into True if integer == 0: truth_value = False else: truth_value = True return truth_value Now, write a function that goes in the opposite direction of the truth_value() function. This new function should convert a truth value into an integer. In particular, True should be converted into 1 and False into 0. Name the new function integer_0_or_1(). All you need to include below is your definition of the function integer_0_or_1(). It will be tested automatically against relevant inputs. So include your function and nothing more.To make a function return more than one result we pass parameters: By value. As int. By void. By reference.Write a function argument_count that accepts an integer i, followed by any number of additional arguments. The function should returnTrue if the value given to i is equal to the number of arguments that follows it, and should return False otherwise.
- Write a function that takes one double parameter, and returns a char. The parameter represents a grade, and the char represents the corresponding letter grade. If you pass in 90, the char returned will be ‘A’. If you pass in 58.67, the char returned will be an ‘F’ etc. Use the grading scheme on the syllabus for this course to decide what letter to return.This is a javascript function. Please input the response of this function in the field below. function test(name, birth_year, current_year) { const age = current_year - birth_year; const response = name + " is " + age; return response;}test("alice", 1823, 1902) Enter the return value of the function.In C, write a function that gets two ints a and b. If a>b the function returns a^3 + b^2, and otherwise it returns a^2 + b^3. int square_cube (int a, int b); For example: square_cube (1,2) should return 1 + 8 = 9. square_cube (10, 3) should return 1000 + 9 = 1009. square_cube (2, -1) should return 8 + 1 = 9. square_cube (-2, -1) should return 4 - 1 = 3.
